Despite five decades of experience, there is a considerable gap in legal and empirical study on the impacts of the National Environmental Policy Act (NEPA). Proponents of reform often claim NEPA litigation is a major obstacle for federal actions; others have concluded litigation is not a major contributor of project cost escalation or delays. This Article studies the incidence and conditions of infrastructure project litigation under NEPA, using a data set of 355 major transportation and energy infrastructure projects that completed a federal environmental study between 2010 and 2018.

The Metals Company (TMC), sponsored by the Republic of Nauru, has made public its intention to be the first company to exploit polymetallic nodules, which contain minerals needed for electric batteries, from the deep ocean’s seabed. Nongovernmental organizations and national governments have objected to these proposed actions, with many calling for an outright ban. This Article offers a case study evaluating the parties’ respective claims in favor of, and in opposition to, permitting the proposed mining activities under the current legal framework.
